Digital color-jet matching technology for gravure printing

Abstract

The invention discloses a digital color-jet matching technology for gravure printing. The technology comprises the following steps: firstly, printing by using a photogravure press to obtain a typography IT8 color test table, and printing by using a digital printer to obtain an IT8 color test table with a print version; secondly, measuring the typography IT8 color test table and the IT8 color testtable with the print version by using a color spectrometer to obtain respective color profiles; thirdly, adjusting color profiles of a digital printer by using color management software through referring to the color profiles of the gravure printing press; fourthly, printing by using the adjusted digital printer to obtain an IT8 color test table with an adjusted print version, and repeating the third step until the color deviation degree of the IT8 color test table with the adjusted print version and the typography IT8 color test table is kept within an acceptable limit. By simulating the printing effect of the photogravure press through the digital printer, a color manuscript is provided for gravure printing, the development cycle of new patterns is shortened, manpower and material resources are reduced and the printing effect is ensured.

Description

technical field [0001] The invention relates to a digital color jet color matching process for gravure printing, which belongs to the field of digital printing. Background technique [0002] In gravure printing, it is necessary to determine the printing effect that can be achieved by printing first, and provide the color sample to the customer for confirmation. Traditional gravure printing needs to engrave the plate roller first in the early stage design and color development and sample confirmation. The cost of plate making is high, and it is not easy to change later. , and in the process of color matching, sampling, and confirmation, it consumes a lot of ink, energy, and paper. It is necessary to repeatedly debug the ink formula, which requires a large investment of manpower and material resources, a long test cycle, and low efficiency. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to overcome the defects of the prior ar...
